How can I copy the area behind my form using the BitBlt?

Hi,
I know that I need to use the BitBlt function, but I don't really know how to make it to copy exactly the area that is behind of my form.


Plese help me out here,

Thanks,
Nahum.

No way to do it except if you hide your form, or have another of your forms behind it

I know that I can take the desktop hdc I can get the desktop image, in the size of my form.

The form will cover the place, it's like taking a screenshot instead.
